Most Republicans still agree with GOP front-runner Donald Trump's call for a temporary ban on Muslims entering the United States months after the presidential candidate first made the proposal in the wake of the San Bernardino massacre in December, according to a new Rasmussen Reports survey.

According to the poll, released on Monday, most favor a ban being enacted until the United States improves its ability to screen out potential terrorists:

67 percent in favor;

23 percent opposed;

10 percent undecided.

The numbers have not changed since early December, the poll found, even though Trump's plan met with condemnation from President Barack Obama, his political opponents, and sources overseas.

The plan even meets with favor among all likely voters surveyed:

45 percent in favor;

42 percent oppose;

12 percent undecided.

And most voters say it's too easy for foreigners to enter the United States legally:

54 percent agree

30 percent think the difficulty is about right;

9 percent think it's too hard.

And among the voters who think it's too easy for foreigners to enter the country, 69 percent favor Trump's call for a temporary ban, while voters think it's too hard to come into the United States or say that the level of difficulty is appropriate strongly oppose Trump's plan.

Rasmussen conducted the survey of 1,000 likely voters on March 30 to 31, and the poll carried a margin of error of plus or minus 3 percentage points, with a 95 percent level of confidence.
